I want to state at the bottom of all pages when the page was last modified. So, I put this line in my standard_html_footer in the root folder: <P>Last modified: <dtml-var last_modified> This results in a Zope Error: Zope Error Zope has encountered an error while publishing this resource. KeyError Sorry, a Zope error occurred. What did I do wrong? Better yet, how does one go about debugging such things? Sorry to ask silly questions, but you've got to start somewhere. Searches for "last_modified" in web resources and in the indices of printed documentation come up empty. -- | Don Porter dgporter@erols.com | | "Some days you just can't get rid of a bomb!" | | -- Adam West as BATMAN | |______________________________________________________________________|
